I have reinstalled Windows on my Office PC and I am stuck with ADE.
I have ebooks that were purchased with two different Adobe accounts. I used to be able to authorize ADE with two accounts and then simply switch between the two accounts using Help/Authorization Information. Now when I authorize ADE with one account, it does not seem to be possible to authorize with a second account, except if I completely delete the first account. In Help/Authorization Information only one account is shown, no matter what I do.
